I know that this is somewhat off-topic here, but not completely :)
I intend to get some mini-boxes
The device gives me all I need except a simple (slow 25HZ) DAC.
All I need is an Output Voltage between 0 and 5 Volts which could be controlled by means of some simple commands.
Do you have any recommondations for this? Some simple schematics are fine as well as the alternative would be a generic IO-Device like the Labjack U12
